Eye of Zebrafish Larva Distinguishes Between Prey and Predator

A new study from the Max Planck Institute for Medical Research reveals how the eye of a zebrafish larva can already distinguish between prey and predator. Red or green? Small or large? Fast or slow? Humans and animals rely on their visual organs to classify objects in their environment. Decisions about how we best respond […]

Brain Structure Could Predict Risky Behavior

New research shows that brain structure may predict risky behavior, revealing that those with a larger volume in a particular part of the parietal cortex were willing to take more risks than those with less volume in this part of the brain. Some people avoid risks at all costs, while others will put their wealth, […]

A New Pathway to Help Treat Perinatal Brain Injuries

A team of researchers has uncovered a new pathway to help treat perinatal brain injuries, revealing that a synthetic molecule derived from the embryo called PreImplantation Factor (sPIF) protects against neuronal death and brain injury by targeting let-7. Researchers at Yale School of Medicine and their colleagues have uncovered a new pathway to help treat […]

Chimps Outplay Humans in Brain Games

In a new study chimpanzees outplay humans in a two-player game, suggesting that chimps may have a superior memory and strategy when it comes to recalling their opponent’s choice history. We humans assume we are the smartest of all creations. In a world with over 8.7 million species, only we have the ability to understand […]

Neuroscientists Reverse Emotional Association of Memories

Neuroscientists from MIT have identified the brain circuit that controls how memories become linked with positive or negative emotions, revealing that they could reverse the emotional association of specific memories by manipulating brain cells with optogenetics. Most memories have some kind of emotion associated with them: Recalling the week you just spent at the beach […]

Neuroscientists Improve Touch Sensitivity in Mice

Neuroscientists from Brown University show that faint sensations can be made more vivid by triggering a brain rhythm that appears to shift sensory attention in mice. This newly published study provides the first direct evidence that the brain’s “gamma” rhythms have a causal role in processing the sense of touch. Providence, Rhode Island (Brown University) […]

Researchers Discover Weakness in Glioblastoma Defenses

By targeting a protein crucial in the early development of the brain, researchers discovered that they can block multiple signaling pathways implicated in glioblastoma growth and have reduced human tumors in mouse models of the disease. Glioblastoma is a complex, deadly, and hard-to-treat brain cancer, but Yale School of Medicine researchers may have found the […]

Researchers Confirm Cellular Basis for Memory by Implanting and Erasing Fear

In a newly published study, scientists at the University of California show the ability to selectively remove a memory and predictably reactivate it by stimulating nerves in the brain at frequencies that are known to weaken and strengthen the connections between nerve cells. Researchers at the University of California, San Diego School of Medicine have […]
